Plugin broke CSS of the site

Strange. Yendif Player have nothing to do with your site’s CSS. Kindly get me your site link. So, I can check what went wrong.

Here is the page url https://www.rad.sik.si/ and this is url (sub-page) where plug-in is used: https://www.rad.sik.si/obrazi-bleda/?avtor=1

Kindly check my screenshot.

I can see everything is normal. Which browser do you use ? I have tested with chrome, Firefox and IE.

It looks like that if I’m not logged in page loaded normally but if I log in than it’s broken. What could be the reason for this strange behavior?
